You guys might be missing the point that i'm trying to make. While "old" speakers may function completely fine, subtle degradation over the years may be tough to notice. The only way to really notice this would be to play a "fresh" set of identical speakers that were "broke in" and do a direct comparison with the "oldies".
In terms of clarifying my statements, i was talking about individual drivers possibly "going soft" due to age, abuse, drying of ferrofluid, thinning of foam surround, softening of the spider or other suspension components, loss of magnetic strength, capacitors drying up or changing value, etc... These are all NORMAL signs of decay and aging that occur to speakers.
Any / all of these things can happen to any one individual driver / part of the crossover in the box or all of them within the system. That is why i mentioned comparing one speaker directly to the other in a side by side mono test. This way, you can make sure that both speakers have similar acoustic surroundings in terms of room loading, etc.. and receive identical signals for comparison. So long as they match relatively closely, that is the bottom line.
I have had friends do similar tests only to find out that the tweeter on one speaker was notably quieter than the other, one mid offered less output than another, etc... A shift of a db or two in ONE driver can alter tonal balance, imaging, soundstage, prat, etc.... The problem is that the damage / decline in performance may have come about so gradually that one would not really notice it under day to day use and conditions. This is not to mention that our ears typically do not get BETTER with age. That is why i recommended taking the time to do some specific testing just to make sure / verify proper operation and even channel balance. Hope this helps.... Sean
